The domestic silica sol production technology mainly comprises an ion exchange method and a silica powder hydrolysis method. In the production process of the silicon powder hydrolysis method, the reaction is carried out in a reaction kettle with mechanical stirring, a common reaction kettle is vertically arranged, and laminar flow is easily generated in the stirring process; the silicon powder can generate hydrogen in the reaction process, and part of the hydrogen can be attached to the fine silicon powder in the reaction process, so that the fine silicon powder floats to the liquid level to form a thick layer of floating objects. Because the silicon powder can be well hydrolyzed only by fully mixing and contacting with the alkali liquor, the silicon powder floating on the liquid surface can not be fully contacted with the liquid, and the reaction speed is reduced. For example, in the conventional solution, CN206008722U adopts a water pump to circularly convey the liquid at the bottom of the reaction kettle to the upper end of the reaction kettle, so as to improve the contact with the silicon powder floating on the liquid surface, but as the reaction proceeds, the liquid at the bottom of the reaction kettle is sticky and easily blocks the water pump; moreover, the liquid to be conveyed cannot be uniformly sprinkled on the silicon powder, and a part of the silicon powder still cannot be in good contact with the liquid.
The existing reaction device generally adds the needed silicon powder and alkali liquor into the reaction device at one time, a large amount of hydrogen is generated by reaction, a pump pot, namely a reaction kettle, is easy to boil, and a large amount of raw material liquid overflows along with a guide pipe. In order to prevent the pan pumping phenomenon, the silicon powder can only be added manually in batches, the participation of operators is high, the feeding time needs to be controlled, and the operation is complicated.
